Collection and usage attributes
|Guide for use:||To determine the bundle-branch block status, compare the current ECG to the preceding or most recently available ECG.|
Record for each ECG that indicates a bundle-branch block is present.
Only one bundle-branch block status can be recorded for each ECG performed.
Only one bundle-branch block can occur at any one time, but in any given person, a left bundle-branch block may occur at one time point and a right bundle-branch block at another time point. Therefore, there can only be one bundle-branch block per ECG, but they may differ temporally.
